Since 1978 until now no less than 80 official world championships in slot-racing were organised. The real first world championship went with G7 wing cars. It was organised at Gotheborg and won by Camen's Joel Montague. Until 1984 there were only world championships for wing cars, and they were organised on even years. Up from 1985 the first world championships for scale cars (soft bodies) and for model cars (hard plastic bodies) were organised.
In total 26 world championships for wing cars were organised, all for Open G7 cars (10 by the USRA, 7 by the ESRAC/ESROC, 4 by the IMCA, 4 by the NPRA).
In scale racing 22 world championships were organised with the first in 1985 (5 by the IMCA, 2 by the NPRA,  and 14 by the ISRA). Until 1992 the ES32 race was the one for the world championship. After 1992 the race with ES24 cars was the world championship's race. The ISRA organises also yearly a team race for 124PR, a race for ES32 and a race for 132F1. Those races are NOT recognized as world championships, since in 1985 the title "world championship", concerning slot-race affairs was patented before notary Ernst von Tricht. Nobody may use the term "world championship" in slot-racing affairs if it concerns other classes than Open G7, ES24, or Model Cars.
In model car racing world championships are exclusively organised by the IMCA, and this since 1985. There were 32 in total: 19 in scale 1/24th, 3 in scale 1/32nd and 10 for juniors. IMCA organises also a world championship (Worlds Concourse) for modelers and for amateurs, but they have never been recognized officially since it was not patented in 1985 before notary Ernst von Tricht. In 2004 and 2005 IMCA organised also a Constructor's World Championship. In 2008 IMCA will organise again an endurance world championship. Since the first edition in Chicago 1988 such event was no more organised.

The 80 official world championships were won by 44 different racers. They are the only ones on earth who can name themselves a slot-racing world champion. The USA won 21 times a world championship, Czechia 11 times, Italy 9 times, Belgium 7 times, the Netherlands 6 times. Brazil won 4 times, Germany, Spain and Sweden won 3 times a world championship. New Zealand won 2 times. Slovakia, Finland and Austria won once. Great nations as the United Kingdom (where slot-racing originated), France, Canada, Japan, South-Africa, Australia, etc. won never an official world championship.

Until now one racer won SIX world championships: Czechia's Vladimir Horky. He won also five ISRA World Cups in ES32. Two racers won five times an official world championship:  "Piki" van Rossem and Nick de Wachter. Two other racers won four world championships:  Czechia's Josef Korec once in wing car racing, once in scale racing and twice in model car racing (Korec is the lonely racer in history having won the world championship in all three the disciplines);  and America's Jan Limpach (twice in model car racing and twice in scale racing). Three racers won three times a world championship: America's Paul Pfeiffer and Paul "Beuf" Pedersen three times in wing car racing; and Italy's Salvatore Noviello once in scale racing and twice in model car racing. Pfeiffer, absolutely unbeatable during the early 1980s, could have won three world championships more, should they have been organised on a yearly basis during that period.
Ten racers won twice a world championship. In wing car racing it were Lasse Åberg from Sweden, P-A Watson from the States, Mario Schöne from Germany, Paul Cicarello from the States, and Mike Swiss from the States. Dave Gick from New-Zealand won twice the world championship in scale racing, just as did Paul Gawronski from the USA. Italy's Sergio Maresca won one a worlds in scale racing (and lost two others after disqualification).  Leo Vogel  from Holland won twice a model car words, just as Daniel Gonzalez who won once the Mello Yello Juniors Worlds and once the Model Car Worlds. The youngest world champion in history is Philip Kremer from Germany. At the age of 15 he won the model car worlds ànd the Mello Yello.
Twenty-seven racers won once a world championship. 43 of the 44 world champions were regular entrants at IMCA races. Not recognized was the victory of America's Matt Zenovitch in the 2002 Mello Yello Junior's World Championship for model cars, since he was the lonely one authorized to drive a MoMo car, whilst all others had to race the old PlaFit chassis. Not (already) officially recognized were the wins of Germany's Matthias Parke at the 2004 Constructor's World Cham-pionship and of Tamar Nelwan (NL) at the 2005 edition. This competition is no longer organised and the titles were never homologated. The non-official world championship for modelers (Concourse) was organised eight times. Here the Brittons won three times, twice with George Kimber and once with Steve Walker. Holland won twice with Hugo Dekker, Slovakia once with Jozef Miskolci, South-Africa won once with Al Paterson, Switzerland once with Gabriël Inabäbnit  and Belgium once with Christophe Boxus. International racing is officially recognized since 1970. There is an all-time ranking of slot-racers, based on all important international races for wing cars, scale cars and model cars, res. since 1970, 1971 and 1985. It is the famous IOC-list. [JPVR]
